Trumpeter Swans are rare but increasing in Pennsylvania, and more are found every year. Many of the swans found in PA have yellow neck-collars or yellow wing-tags from the Ontario reintroduction efforts. However, there has been an interesting rush of sightings of 3 different neck-collared Trumpeter Swans in PA since March 10th; all of which have stained, white neck-collars with 4-digit codes on them starting with Z6.
Trumpeter Swan Z639 was sighted in Adams and Cumberland Counties over the course of a few days, and then a pair of swans (Z603 and Z675) were discovered in Schuylkill County, and have even been observed copulating. According to the Bird Banding Lab, these swans are not in their database, and the bander using this pattern is now inactive, and the lab never received any data on these swans, and this collar color and pattern expired in 2002. According to swan banding protocol, this pattern of neck collar was used on ‘captive’ swans (Trumpeters, Tundras, and Mutes) in MD, PA, VA, and OH.
Where did these swans come from? A private collection?….it’s easy to find Trumpeters for sale online. Why are these just turning up suddenly in the past month when they were probably banded in 2002 or earlier? Does anyone know of any waterfowl collectors missing their swans?
